Since it is really the grandfather to the iPod and iPhone.

But it didn't make a splash when it launched. Mostly because it didn't have the Internet (at least I don't think. And even if it did, it would have been a lesser user experience than the browsing on the iPhone.) and was too ahead of its time. Really all of those PDA's developed were. With the exception of the Palm devices I don't think they caught on with anyone who wasn't a fierce early-adopter.
